, To all whom it may concern:

Improvements in Hose Nozzles or Pipes; and

l do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich` it appertains to make and use the same, reference being had tothe accompanying drawings, and to letters of reference marked thereon,which form a part of this specification.

The object of my invention is to produce a nozzle or hose-pipe (moreVespecially intended for fire extinguishers containing carbonicacid orother gas) thatis very simple in its construction and not liable to getout of order.

Hitherto hose pipes have been provided with an ordinary plug-cock,secured therein, which is liable to corrode or become stuck in itsplace, so that it cannot be operated, and they are thereforeveryunreliable.

To obviate these difliculties is the object of my invention; and itconsists in providing the hose-pipe for fire-extinguishers, containingcarbonio-acid or other similar gases, with a valve, which has its seaton the outer end of the pipe, and, moving at right angles to the axis ofthe pipe, closes its mouth securely.

This'valve is formedv and operated either by a pivoted bentspring-lever, or a pivoted revolving bent lever working against a cam,or a forked hinged or swinging lever, having' anV eye in its outer end,through which a screw, with an enlarged `end containing thevalvepacking, moves; or, instead 'of the screw, it may be a plain stem,around which is arranged -a coiled spring, by which the valve is seatedwhen the lever is in position.

In the accompanying drawing, Figure l represents a hose-pipe, partly insection, with a bent pivoted spring-lever. Fig. 2 is a hosepipe with arevolving lever, provided with a lug to engage with a camlip. Fig. 8 isa hosepipe with aV hinged forked lever, having a screw to secure thevalve in place. i Figs. 4 and 5 are side and end views of a hose-pipewith a hinged or swinging forked lever, with a plain stem and coiled`spring to secure the valve to its seat.

In the drawing, A represents an ordinary hose pipe'or nozzle, and inFig. l a lug, a, is secured thereto, to which the lever B is pivoted. Atits upper end this lever is bent at right angles, as shown at b, and inits face is inserted a piece of vulcanized rubber, c, or other suitablenon-corrosive material, which forms the valve, and may be adjusted, incase of wear, by a set-screw, d. A spring, b, is secured to the insideof the lever B, by which the valve is always kept closed over the mouthof the nozzle until pressed upon by the hand when it is desired to openit for use.

In Fig. 2 is shown a modification, in which the lever B is pivoted onone side of the hosepipe, as shown at c, so as to revolve horizontallyto the axis of the pipe. It is provided with rubber or other suitablematerial c, and is held to its seat by a cam-lip or flange, f, withwhich the lug g, on the lever B, engages,

and as the lever is moved around on its pivot, l

it firmly secures the valve in its position by means of said cam and lugon the lever B.

In Fig. 3 is represented a pipe with a forked or swinging lever B, whichis pivoted at h h, so as to move with its outer connected end freelyover the mouth of the pipe. In the cross-piece o of the lever B isarranged a screw, t', provided with a small hand-wheel, lo, at one end,while the other end is enlarged to receive the rubberor other suitablepacking c.

When the lever is brought over the mouth of the pipe it is onlynecessary to screw the valve down to its seat to firmly close it, andwhen the screw is loosened the valve can be moved to one side or theother of the pipe.

In Figs. 4 and 5 is shown a modification of Fig. 3, the same form ot'forked lever B being used and pivoted at h h. Instead of the screw i,however, the valve-stein l is plain, and is provided with a coiledspring, m, arranged between the enlarged end n of the stem and thecross-piece o of the lever B. rlhe stem L is also provided with a smallwheel or handle, p, bywhich to draw the valve from its seat, and swingit and the lever B to one or the other side of the hose-pipe.

Many other modifications might suggest themselves to any one skilled inthe art, but I have only shown a few instances. They may be made of anysuitable material, and of any size and configuration desired.

The advantages of 'my improved hose-pipe are, that it is not liabletoget'outoforder; there is no possibility of corrosion; it is verysimple in its construction, can` be easily repaired, and can befurnished at a very low and reasonable cost.

Having thus described my invention, what I claim, and desire to-secureby Letterslat-h lsubstantially as s hown and described.

In testimony that I claim the foregoing as 4myown I hereby affix mysignature in pres- 61108 0f WO Witnesses.
